Table 16. Line Flyback Input (Pin 18)
Note: 1. An RC network is connected to this input. Typical value for the resistor is 27kΩ and 220pF for the capacitor. A different time constant
for RC changes the delay between the middle of the line synchro pulse and the leading edge of the burst key pulse but also the
duration of the burst key pulse.
